Drogue shear pins eliminated. Main shear pin holes reinforced with copper shim stock. Hole in nosecone taped t' reduce volume t' pressurize. Beeper eliminated because unable t' initialize after multiple attempts. Some weather-cocking, probably due t' relatively low speed off-the-rail. Straight flight. Both drogue charges fired on schedule; separation occurred, but drogue did nay deploy because it was anchored too close t' t' body tube. Both main charges fired on schedule; main chute deployed perfectly. No damage.
